Chinese Researchers Set New Solar Cell Efficiency Record with Tandem Technology

Recent advancements and initiatives in solar technology highlight ongoing efforts to improve efficiency, affordability, and sustainability. In Uttar Pradesh, the Yogi government is empowering women through training in solar panel installation and EV charging under the DEWEE program, promoting economic empowerment. Research groups are developing alternatives to silicon solar cells, such as stabilized perovskite cells enhanced by titanium vapor-phase infiltration, addressing their durability issues, particularly under high temperatures. Chinese researchers set a new record with silicon-perovskite tandem solar cells achieving 34.58% efficiency, nearing theoretical limits and promising lower costs and increased rooftop solar adoption, though further testing for environmental durability is needed. Korean scientists have created bendable, moisture-resistant perovskite solar panels that maintain high efficiency and mechanical resilience, enabling cheaper production without climate-controlled facilities. Additionally, Chinese researchers have innovated a chemical-free, thermally based recycling method for PV ribbon, a key component of solar panels, which recovers valuable metals efficiently, reducing environmental impact and costs.
